||Standard delivery of ACS WFC superbias, superdark, and sink pixel reference files following the anneal on January 2, 2019. These files will be used to calibrate ACS WFC observations taken between December 6, 2018 and January 2, 2019. Delivered by Tyler Desjardins for ACS.
||A new blob appeared on Dec 12, 2018. The effect of the blob was noticeable enough to warrant the creation of a new bad pixel table, so that the blob will be flagged in DQ arrays. Delivered by Ben Sunnquist for WFC3.
||This includes two STIS deliveries. The reason is new weekly STIS biases and darks created for the new anneal months of Oct and Nov need to be delivered for GO observations
||WFC3 had an error in the USEAFTER date for file 2ck18541i_bpx.fits, this incorrectly removed u5d2012li_bpx.fits from the rmap. USEAFTER of the new file was fixed in the rmap and the 2009 bpix file was put back in the rmap. The USEAFTER in the header of the 2ck18541i_bpx.fits file was not modified.
